Calibrachoa plant named ‘Sunbelkopawai’

ABSTRACT

A new and distinct cultivar of  Calibrachoa  plant named ‘Sunbelkopawai,’ characterized by its compact and mounding plant habit; moderately vigorous growth habit; freely branching and flowering plant habit; early and long flowering period; purple-colored flowers; and good garden performance.

Botanical designation: Calibrachoa sp.

Cultivar denomination: ‘Sunbelkopawai’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Calibrachoa plant, botanically known as Calibrachoa sp. and hereinafter referred to by the name ‘Sunbelkopawai’.

The new Calibrachoa plant is a product of a planned breeding program conducted by the Inventor in Higashiomi, Shiga, Japan. The objective of the breeding program is to develop new compact, mounding and freely-branching Calibrachoa cultivars with attractive and unique flower coloration .

The new Calibrachoa plant originated from a cross-pollination conducted by the Inventor in Higashiomi, Shiga, Japan in April, 2004 of a proprietary selection of Calibrachoa sp. identified as code number LBS68, not patented, as the female, or seed, parent with a proprietary selection of Calibrachoa sp. identified as code number LBS83, not patented, as the male, or pollen, parent. The new Calibrachoa was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Higashiomi, Shiga, Japan in September, 2005.

Asexual reproduction of the new Calibrachoa plant by vegetative cuttings in a controlled greenhouse environment in Higashiomi, Shiga, Japan since October, 2005, has shown that the unique features of this new Calibrachoa plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Calibrachoa have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Sunbelkopawai’. These characteristics in combination distinguish ‘Sunbelkopawai’ as a new and distinct cultivar of Calibrachoa:

-   -   1. Compact and mounding plant habit.     -   2. Moderately vigorous growth habit.     -   3. Freely branching and flowering plant habit.     -   4. Early and long flowering period.     -   5. Purple-colored flowers.     -   6. Good garden performance.

Plants of the new Calibrachoa can be compared to plants of the female parent selection. Plants of the new Calibrachoa differ primarily from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Calibrachoa are more compact than plants of         the female parent selection.     -   2. Plants of the new Calibrachoa and the female parent selection         differ in flower color as plants of the female parent selection         have red purple-colored flowers.

Plants of the new Calibrachoa can be compared to plants of the male parent selection. Plants of the new Calibrachoa differ primarily from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Calibrachoa are more compact than plants of         the male parent selection.     -   2. Plants of the new Calibrachoa and the male parent selection         differ in flower color as plants of the male parent selection         have red purple-colored flowers.

Plants of the new Calibrachoa can also be compared to plants of ‘Sunbelochipi’, disclosed in U.S. Plant Pat. No. 10,355. In side-by-side comparisons conducted in Higashiomi, Shiga, Japan, plants of the new Calibrachoa and ‘Sunbelochipi’ differed primarily in the following characteristics:

-   -   1. Plants of the new Calibrachoa were more compact and mounding         than plants of ‘Sunbelochipi’.     -   2. Plants of the new Calibrachoa were not as vigorous as plants         of ‘Sunbelochipi’.     -   3. Plants of the new Calibrachoa were more freely branching than         plants of ‘Sunbelochipi’.     -   4. Plants of the new Calibrachoa had smaller leaves than plants         of ‘Sunbelochipi’.     -   5. Plants of the new Calibrachoa flowered earlier than plants of         ‘Sunbelochipi’.     -   6. Plants of the new Calibrachoa and ‘Sunbelochipi’ differed in         flower color as plants of ‘Sunbelochipi’ had red purple-colored         flowers.
